QuEChERS method and pre-mixesWithin a few years after its devleopment by Anastassiades et al. the QuEChERS method has gained a leading position for determination of pesticide residues in food by GC-MS or LC-MS allowing rapid and cheap clean-up of strong matrix-contaminated samples.Standard clean-up of food samples10 g sample are homogenised with 10 ml acetonitrile. After adding the internal standard the sample is shaken with 4 g MgSO4 and 1 g NaCI and afterwards centrifuged. 1 ml of the supernantant is spiked with 25 mg CHROMABOND® Diamino and 150 mg MgSO4 and shaken again. After centrifugation the supernatant is injected into the GC/MS.Empty PP centrifuge tube with screw cap, 50 ml, without QuEchERS mixtures.

For improved volatility, better thermal stability or low limit of detection in gas chromatography prerequisite: quantitative, rapid and reproducible formation of only on derivative halogen atoms introduced by derivatisation (e.g. trifluoroacetates) allow specific detection (ECD) with the advantage of high sensitivity elution order and fragmentation patterns in MS can be influenced by a specific derivatisation.Reagents for silylation - alkylation (methylation) - acylation are available.Acylation with fluorinated acid amides is recommended for alcohols, primary and secondary amines as well as for thiols under mild, neutral conditions. MBTFA also forms very volatile derivatives with carbohydrates.by-products: corresponding neutral acylamides, which can be easily removed due to their high volatility; because of neutral conditions and favourable chromatographic properties often removal of the bisacylamide is not necessary. Thus sample preparation is much more convenient.MBTFA / MBHFBAN-methyl-bis(trifluoroacetamide) MBTFAm.w. 223.08, Bp 123 - 124°C (760mm Hg), density d20°/4° = 1.55,CF3 - CO - N(CH3) - CO - CF3Due to their purpose, derivatisation reagents are very reactive substances. For this reason they should be stored cool and protected from moisture.The derivatisation reagents are supplied in vials with crimp caps for easy access with a syringe. Vials with pierced sealing disks have limited stability and should be used soon.Hazardous Substance DataGHSSignal wordGefahrH-SatzH226, H302, H314US, H315, H319P-SatzP260D, P280sh, P303+P361+P353, P305+P351+P338, P501SDSLink
